Array and string Array is a very basic data structure representing a group of similar elements, accessed by index. Array data structure can be effectively stored inside the computer and provides fast access to the all its elements.

Let us see an advantages and drawbacks of the arrays. Advantages Any element of an array can be accessed at O 1 time by its index. Drawbacks Array data structure is not completely dynamic.

Many programming languages provides an opportunity to allocate arrays with arbitrary size dynamically allocated arraybut when this space is used up, a new array of greater size must be allocated and old data is copied to it.

Insertion and deletion of an element in the array requires to shift O n elements on average, where n is size of the array. Static and dynamically-allocated arrays There are two types of arrays, which differ in the method of allocation.

Static array has constant size and exists all the time, application being executed. Dynamically allocated array is created during program run and may be deleted when it is not more needed.

Dynamically allocated arrays can be quite large, even bigger, than amount of physical memory. Yet, dynamically allocated array can not be resized.

But you can expand an array as noted below: Create new array of bigger size; Copy data from old array to the new one; Free memory, occupied by the old array.

Fixed-size and dynamic arrays As it mentioned above, arrays can't be resized. In this case array is called fixed-size array. But we can use a simple trick to construct a dynamic array, which can be resized. The idea is simple.

Let us allocate some space for the dynamic array and imaginary divide it into two parts. One part contains the data and the other one is free space.

When new element is added, free space is reduced and vice versa. This approach results in overhead for free space, but we have all advantages of arrays and capability of changing size dynamically.

We present some definitions about this kind of arrays below.

Dynamic array has its capacity, which shows the maximum number of elements, it can contain. Also, such an array has the logical size, which indicates, how much elements it actually contains. For instance, we would like to find minimum of the values user entering.

We allocate space to store 15 elements, but user has entered only 5 numbers. In the example, capacity of an array is 15 elements, but logical size is 5 elements. When dynamic array becomes full, it must be expanded by creating new larger array and copying elements from the old array to the new one.

Notice, that copying arrays is supported by the hardware and can be done very efficiently. Dynamic array with capacity 10, logical size 5.On Windows, the standard line break is \r\n, not \vetconnexx.com the stream is opened in text mode (the default), std::ofstream should automatically convert \n to whatever the OS's standard line break is.

If that is not happening for you, then either you opened the stream in binary mode, or you have a buggy STL implementation. C Program to Find the Sum and Average of Numbers Using Do-While Loop.

C++ Program to calculate sum and average of three numbers - The Crazy Programmer

Steps: Declare two integers i and n and also initialize i with 0. Declare three floats sum, . Is it possible to have char *s to work with utf8 encoding in C++ (VC)?

For example if my source file is saved in utf8 and I write something like this: const char* c = . All variables use data-type during declaration to restrict the type of data to be stored.

Therefore, we can say that data types are used to tell the variables the type of data it can store. Whenever a variable is defined in C++, the compiler allocates some memory for that variable based on the data-type with which it is declared. This program takes n number of element from user (where, n is specified by user), stores data in an array and calculates the average of those numbers.

To understand this example, you should have the knowledge of following C programming topics. C Program Write a Program to Sum of N Number. C Program Using Structure to Calculate Marks of 10 Students in Different Subjects.
